How to calculate Speed and Acceleration
How to Calculate Speed and AccelerationSpeedSpeed- the distance traveled divided by the time during which the motion occurred. Constant Speed- movement at a fixed distance per unit of time. The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. Instantaneous Speed-is the velocity of an object at a certain time. For example:- Suppose you are driving in a car with your father see the speedometer, its speed constantly varies, Because speedometer give speed at a particular moment of time.

Distance
TimeTime
Variables Expressed byDistance can be expressed inkm (kilometers), mi (miles), m (meters), ft (feet).Time can be expressed inHours, minutes, seconds, days.Speed can be expressed inm/s (meters per second), c/s (centimeters per second), km/ hr/ sec (Kilometers per hour over seconds).Determine which one is which
